Title: Improvements relating to lifc-saving tubes for sunken submarines
IPC: B63G8/40
Filed: 1921-03-07
Abstract: 181,440. Willcock, W. H. March 7, 1921. No Patent granted (Sealing fee not paid). Buoys.-A life-saving tube, through which the crew may be drawn to the surface, is drawn down from a surface vessel and fixed in operative position to a .sunken submarine without the aid of divers. A buoy A, Fig. 1, normally carried on the deck of the submarine, contains two drums D carrying cables, the ends of which are attached to the buoy and led under pulleys P on the deck of the submarine. The buoy is normally held in position by screwed clamps C carried by a detachable bar inside the submarine. When the submarine sinks, the clamps are operated to release the bucy which rises to the surface. The ends of the cable are then detached from the buoy and drums D respectively and the cables are employed to draw stouter cables down around the pulleys P. The stouter cables are then attached to lugs L on the relief tube T, Figs. 2 and 3, which is drawn down to the submarine by hauling on the other ends of the cables. A flange F on the tube is engaged by spring clamps C' and held securely against a corresponding flange on the submarine. Anv water held between the manhole cover M and the tube is allowed to escape through a valve V. The manhole cover M and the cover H on the end of the tube are then removed by the submarine crew, and additional clamps X secured in position. The crew are then drawn up in succession through the tube by means of a rope, which is of sufficient length to enable it to be drawn down by the remaining members of the crew. The buoy A, in leaving the submarine, may carry with it an electric cable which may be used for telephonic communication with the salvage boat, or for igniting a flare carried by the buoy.

Filed: 1948-03-11
Abstract: 639,354. Yielding-drive tapping machines. NORBURY, E. March 11, 1948, No. 7444. [Class 83 (iii)] [Also in Group XXXV] A tapping or like machine has the direction of rotation of the cutting tool temporarily reversed when loaded to a predetermined extent and includes relatively rotatable magnet and armature elements coacting with one another for transmitting torque to the tool until the torque exceeds a predetermined value dependent upon the magnetic flux, whereupon slip will occur and the driven element will " kick lock " temporarily reversing the drive. The spindle 12 may be driven from an electric motor and is secured to two non-magnetic cheekmembers 27 enclosing and attached to a horse-shoe magnet element 20 with poles 21. The cheek members are secured at 26 to a cylindrical non-magnetic casing 25 within which an armature 22 is rotatable. The latter is keyed to the spindle 17 which drives the tap 14 through a pin-andslot connection 16. The magnet may be permanent or an electro-magnet and in each case the flux may be varied to give a torque of predetermined magnitude.

In a modification an extension bar, adapted to telescope with respect to the stay bar 1, carries at its one end 'the guide member 9 and is pivoted at its other end to the window. In a further modification the grooved member is attached to the sill, the guide member being pivoted to one end of a plain stay bar pivoted at its other end to the window. It is stated that the members may be die cast from light metal alloys. The Provisional Specification states that a link member may be 'interposed between the stay bar and the window, the pivotal axes at the ends of the link being at right angles to one another.

The novel prostaglandins 1α - (6 - carboxyhexyl) - 4α - hydroxy - cyclopentan - 2 - one having in the 5#-position a 3S-hydroxy-n-alklt-enyl group of 7 or 9 carbon atoms (alternatively named #-nor- and #-homo-prostaglandins E 1 ) and the novel salts and esters thereof are prepared by aerobic incubation of nonadeca- or heneicosa-8c,11c,14c-trienoic acid with a prostaglandin-synthesizing enzyme prepared from animal tissue, e.g. sheep vesicular gland, desirably in the presence of added glutathione. The required products can be isolated as the free acids and, if desired, converted into salts or esters of the carboxylic group. The free acid can be regenerated from its derivative if required. The starting acids can be prepared by selective partial hydrogenation from the corresponding triynoic acids (themselves prepared from non- 8-ynoic acid, ethyl magnesium bromide and 1 - bromo - deca - 2,5 - diyne or 1 - bromododeca-2,5-diyne) or by chain-lengthening of the corresponding trienoic acids of one carbon atom less by the Arndt-Eistert synthesis. Salts of these acids and their methyl esters are also described. The prostaglandins of the invention are stated to exhibit smooth muscle-contracting hypotensive, heart-stimulating and/or blood platelet aggregation-inhibiting activity, and they may be made up into pharmaceutical compositions with suitable carriers.

Abstract: 434,823. Resistance measurements. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. March 10, 1934, No. 7718. Convention date, March 16, 1933. [Class 37] In a bridge for measuring an earth resistance x by the aid of two auxiliary earths y, z, one of which is connected to the indicator diagonal 1, 2 of the bridge and the other to a bridge arm, the ratio between two arms of the bridge, one of which includes one of the auxiliary earths, is determined by reactive impedances. In the arrangement shown, the impedances comprise equal condensers Cp, Cf arranged in adjacent arms 1, 4 and 2, 4 of the bridge, the remaining arms 2, 3 and 3, 4 comprising the earth resistance x to be measured and an adjustable resistance r. The indicator diagonal of the bridge, including the telephone H, is connected to a contact sliding on a resistance R, and the point 4 of the bridge to a contact sliding on a resistance RI arranged between the condensers. When the bridge is balanced, the earth resistance x is equal to the portion r of the resistance R in the arm 1, 3 of the bridge. The resistance R may be shunted by resistances R<1>, R" to obtain different measuring ranges. In a modification, Fig. 3 (not shown), the reactive impedances comprise coupled inductances, the point 4 of the bridge being connected to the middle point of an inductance coil. Instead of employing reactive impedances of the same sign in adjacent arms of the bridge, impedances of opposite sign may be employed in opposite arms.

Title: Improvements in detergent compositions
Inventor: HODGE ARTHUR
IPC: C11D3/22
Filed: 1952-03-31
Abstract: Aqueous solutions of anion-active detergents, e.g. higher alkyl sulphates and sulphonates, are thickened by incorporating therewith a methyl cellulose of a methoxyl content above 30 per cent and a viscosity above 750 c.p.s., as determined in 2 per cent aqueous solution at 20 DEG  C.  The concentration of methyl cellulose in the solutions may be 0.4-2 per cent.  The viscosity of the solutions may be further increased by the addition of a salt, e.g. sodium, potassium or ammonium chloride or sulphate, but the concentration of salt in the solutions should not exceed 5 per cent, and account should be taken of any salt, e.g. sodium sulphate, present in the detergent.  The thickened solutions may be made by adding the methyl cellulose to the detergent solution, heating the mixture to 80-90 DEG C. and then cooling it while stirring, the process being repeated if necessary. Alternatively, an aqueous solution of the methyl cellulose may be added to the detergent solution.  Examples are given of the preparation of thickened solutions of the detergent sold under the Registered Trade Mark "Teepol."
